Difference Between Carburetor And Injection

In combustion engines for 2-wheeled vehicles or motorcycles, there are 2 types of fuel and air mixing systems, namely the carburetor system and the injection system. The second aims to mix fuel and air with the right ratio.

Carburetor

The carburetor uses a low-pressure airflow generated by the movement of the piston on the intake stroke. Carburetors only depend on piston movement to mix fuel and air, the faster the piston movement, the faster the air flow in the venturi carburetor, the lower the pressure on the venturi and the easier it is for fuel to move to the venturi.

The fuel mixture ratio does not change at each RPM as long as the carburetor is not adjusted.

Injection System

Meanwhile for the injection system, the amount of fuel that is mixed is already regulated by the ECU or electronic control unit, where the amount of fuel that is sprayed by the injectors is regulated by the ECU taking into account various inputs from sensors, these sensors include throttle sensor opening or gas opening. , temperature sensor, intake manifold pressure, oxygen level sensor, tilt sensor, crankshaft sensor, engine speed etc.

So the amount of fuel that is mixed at each RPM is different at the injector, for example when the sensor detects an engine that is still cold the ECU will respond by providing more fuel so the engine heats up faster, so the injection engine does not need a choke, or for example on high rpm, if the oxygen sensor detects high oxygen levels in the rest of the combustion is the engine lack of fuel then the ECU will add fuel supply so that the engine does not lose power. Likewise, other sensors can affect the ECU to regulate fuel supply. So, the injection system is dynamic, where at every engine speed the ECU has been programmed to make adjustments taking into account various conditions, so that the injectors can provide the right fuel supply to the combustion chamber, without input from these sensors, the injectors will experience lack or excess of fuel supply, making the injection system environmentally friendly and more efficient than static carburetors.

In addition to these advantages, the injection system also has several disadvantages, the injection system relies heavily on input from sensors and also the vehicle's electricity itself, so that if one is damaged it will cause problems and the fuel supply will also have problems, the engine can lack power, wasteful. fuel or cannot be ignited.

While the carburetor is a component whose work is driven mechanically, so that its performance does not depend on other components, it only depends on the engine speed, in addition to the cheaper price, the carburetor is also easy in terms of maintenance and adjustment.

That's my brief discussion about the difference between a carburetor and an injection system, I hope it's useful.

Text And Mtext In Autocad

The Difference Between "Text" And "Mtext" In Autocad And How To Convert It In operating AutoCAD we often encounter or use writing with the aim of providing information, showing something, etc. so that our drawings are easier to understand. To write in AutoCAD, we know that there are two options, the first is "TEXT" and the second is "MTEXT". So what are the differences between the two? TEXT For "text" itself we can call it single text or single writing. So if we use "text" we can only write one sentence in one piece of text. The disadvantage of this "text" is that it doesn't have any editing menu, we can't adjust or adjust our needs in this paper, instead we must first enter the properties menu. This means that from this "text" we can only edit the written content. To use this "text" we can use the command type "DT" then press enter. MTEXT As for "mtext" itself is an ab

Genset Heating Procedure

Genset Heating Standard Procedure Genset is one of the equipment that functions to convert mechanical energy or rotation of the rotor into electrical energy. The generator has two main parts, namely the motor generator and the generator engine (usually a diesel engine), both of which are connected by a shaft. The generator itself has two main parts, namely the rotor and stator. The stator is the stationary part, while the rotor is the rotating part. This generator works when the genset control panel receives input if the power source from PLN dies, then the PLC or ATS (automatic transfer switch) will give an order to the genset control panel to turn on the generator, this is done automatically. What if the generator has to be turned on manually, for example when heating the generator? Genset as one of the supporting utility facilities of a building must of course be maintained regularly, one of which is heating the generator as one of the genset maintenance procedures. To warm up the g
